Acknowledgement Mode 

The type of acknowledgement used with HL7 transaction. Choose one of the following options:

• Original: An acknowledgement is sent from the receiving system's application layer once the application has successfully processed the message. This is also called the Application Acknowledgement.

• Enhanced: Both the Application Acknowledgement (Original Acknowledgement) and an Accept Acknowledgement are sent from the receiving system. The Accept Acknowledgement is sent once the message has been committed to safe storage and acknowledges that there is no need to resend the message.
